North Korean leader Kim Jong-Un said Pyongyang would not sit idly by "with rabid dogs barking" about toppling its socialist system, in apparent reaction to comments by US President Barack Obama that the regime was doomed, state media reported Saturday.

Kim made the remarks while overseeing a joint naval and air force drill simulating an attack on a US carrier strike group off South Korea, the Korean Central News Agency (KCNA) said. (Reuters)
